{"product_id":"castaldo-gold-label-natural-molding-rubber-5lb-roll","title":"Castaldo Gold Label Natural Jewelry Molding Rubber-5 lb Roll","description":"\u003cp\u003eCastaldo Gold Label Natural Jewelry Molding Rubber is the premium choice for experienced mold-makers tackling complex, detail-demanding work. Formulated with even more pure natural gum rubber than Castaldo White Label, Gold Label delivers exceptional softness and pliability — qualities that make it indispensable when working with difficult molds that contain undercuts. A stiffer compound in these situations risks breaking delicate wax patterns or making their production impossible. Gold Label's superior flexibility helps protect intricate wax patterns and can significantly reduce labor costs over time.\u003c\/p\u003e\u003cp\u003ePlease note: Castaldo USA has been acquired by a company in the United Kingdom, and all Castaldo products are now manufactured in the UK. Castaldo Gold Label Natural Mold Rubber is no longer available in strips or pre-cut form — it is available exclusively in 5 lb rolls.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eHigher concentration of pure natural gum rubber than Castaldo White Label\u003c\/li\u003e\n\u003cli\u003eExceptionally soft and pliable — ideal for molds with undercuts\u003c\/li\u003e\n\u003cli\u003eHelps prevent breakage of delicate wax patterns during demolding\u003c\/li\u003e\n\u003cli\u003eReduces labor costs on difficult or complex mold work\u003c\/li\u003e\n\u003cli\u003eAvailable exclusively in 5 lb roll format\u003c\/li\u003e\n\u003cli\u003eNow manufactured in the United Kingdom\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight\u003c\/th\u003e\n\u003ctd\u003e5 lb roll\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVulcanizing Temperature\u003c\/th\u003e\n\u003ctd\u003e310°F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eVulcanizing Time\u003c\/th\u003e\n\u003ctd\u003e15 minutes per 1\/4\" of mold frame thickness\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCompound Base\u003c\/th\u003e\n\u003ctd\u003eNatural gum rubber\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCountry of Manufacture\u003c\/th\u003e\n\u003ctd\u003eUnited Kingdom\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eNotes\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCastaldo Gold Label is no longer available in strip or pre-cut formats — 5 lb rolls only.\u003c\/li\u003e\n\u003cli\u003eCastaldo products are now manufactured in the United Kingdom following the acquisition of Castaldo USA.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Castaldo","offers":[{"title":"Default Title","offer_id":43584824934614,"sku":"122.596","price":63.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/castaldo-gold-label-natural-jewelry-molding-rubber-5-lb-roll-otto-frei.jpg?v=1719955905","url":"https:\/\/www.ottofrei.com\/products\/castaldo-gold-label-natural-molding-rubber-5lb-roll","provider":"Otto Frei","version":"1.0","type":"link"}
